Synaesthesia is a truly fascinating condition. In its simplest form it is best described as a “union of the senses” whereby two or more of the five senses that are normally experienced separately are involuntarily and automatically joined together. Some synaesthetes experience colour when they hear sounds or read words. Others experience tastes, smells, shapes or touches in almost any combination. These sensations are automatic and cannot be turned on or off. Synaesthesia isn’t a disease or illness and is not at all harmful. In fact, the vast majority of synaesthetes couldn’t imagine life without it.

The UK Synaesthesia Association was originally founded by Professor Simon Baron-Cohen, Professor of Developmental Psychopathology at Cambridge University and a leading researcher into the phenomenon. Operating as a non-profit making organisation, the Association brings scientists, researchers, students and synaesthetes together and provides verifiable and reliable information regarding the condition for the media and any other interested parties. The Association has a dedicated committee made up of researchers and synaesthetes who meet regularly, and produces an entertaining and informative quarterly newsletter for its members. We also hold an annual international conference with eminent guest speakers including scientists, researchers and synaesthetes themselves. Our national and international membership base is ever-growing and of course we welcome any new members, whether they are synaesthetes or simply those with an interest in Synaesthesia.

Within this website you will find useful links to web-based discussion forums where synaesthetes and non-synaesthetes can share information and contact researchers conducting experimental investigations in order to further our understanding of synaesthesia. There are also links recounting the history of the study of synaesthesia, media articles, research papers and lots of other interesting, up-to-date information for synaesthetes, academics, researchers, scientists, artists, writers, musicians and journalists.

On behalf of the UK Synaesthesia Association, I welcome you to our website.  We hope you find these resources useful and we welcome your feedback.  Please send any questions, comments or recommendations to:
